以上是我的bean配置，为什么我运行我的应用程序时会出错。我的日志文件夹是空的......

但我已将spring-web-mvc添加到包含此类文件的类路径中。

2 个答案:

答案 0 :(得分：4)

  

但是我已经将spring-web-mvc添加到我的   包含这个的类路径   类文件。

你是如何向CLASSPATH添加内容的？

如果您正在创建一个Web应用程序，唯一合适的方法是将.class文件放在WEB-INF / classes和WEB-INF / lib下的.jar文件下。如果你做了别的什么，我会说这是错的。不应该修改启动脚本;本地环境变量将被忽略，并且不太可能在您部署到的服务器上设置。

更新：

如果你告诉我你已经根据你的IDE做了一切，我建议你最后检查一下：查看你实际部署到Tomcat的压缩或爆炸的WAR文件，并确保你可以看到JAR使用错误提到的.class文件。如果它不是WAR的一部分，你必须弄清楚你的包装出了什么问题。如果你认为JAR在那里，打开它并找到.class并检查路径。

您必须相信您看到的错误消息。而不是说“我做的一切都是正确的”，最好说“我错过了什么？”

答案 1 :(得分：3)

ClassNotFoundException表示你不在类路径上有Spring。确保它在WAR的lib目录中。

另外，请确保您的类路径中还有commons-logging.jar。春天取决于此。
